Hi Xianfei,

if you are interested, we have formally analyzed the difference between 
orchestration and choreography in

"Choreography and Orchestration conformance for system design"
Nadia Busi, Roberto Gorrieri, Claudio Guidi, Roberto Lucchi and 
Gianluigi Zavattaro
In Proc. of 8th International Conference on Coordination Models and 
Languages (COORDINATION'06).
Volume 4038 of LNCS, pages 63-81, 2006.

where we have proposed two formal calculi for choreography and 
orchestration respectively. Moreover, we have proposed a relationship 
between them which resembles a bisimulation realtion. In my PhD thesis 
you can find this topic deeply analyzed:
http://www.cs.unibo.it/pub/TR/UBLCS/ABSTRACTS/2007.bib?ncstrl.cabernet//BOLOGNA-UBLCS-2007-07

Other very interesting formal works about choreography and orchestration 
are the following one:
"Structured Communication-Centred Programming for Web Services"
Marco Carbone, Kohei Honda and Nobuko Yoshida.
ESOP 2007

"A Rigorous Approach To Engineering Web Service Compositions."
Howard Foster.
PhD. thesis, Imperial College London, University of London, Department 
of Computing, 2006.

Regards,
CG
